- In May 2020 Shore Monitoring and Research installed two GNSS loggers at the Veenweiden Innovatiecentrum in Zegveld
to monitor ground motion in the framework of the Nationaal Onderzoeksprogramma Broeikasgassen Veenweiden (NOBV).
The GNSS loggers are located in plot number 16 at the most Southerly measurement location.
One GNSS antenna is installed on a grid to monitor the motion of the top soil, the second antenna is mounted
on a Ground Control Point (GCP) connected by a pile to a stable sand layer.
- 2024-10-22T15:00Z 2337/2 296 -
- In October 2024 TU Delft took over responsability for the GNSS loggers and processing
from Shore Monitoring and Research. New receivers were installed
and site operation switched from Solar power to AC mains, but the antenna's remained the same.
- 2020-05-07T13:00Z 2104/4 128 -
- The GNSS ground motion loggers are located at the most Southerly measurement location of plot 16. This is about 250 meters
South of the Integrated Geodetic Reference Station (IGRS), at
plot 15 of the Veenweiden Innovatiecentrum, which is also operated by TU Delft. The Integrated Geodetic Reference Station
(Zegveld IGRS) is used as base station in the processing.

- In the period between May 2020 and July 2022 the two receivers at plot 16 were programmed to collect data at a
frequency of 1 Hz for the full 24 hours of a day. This resulted in several outages during the winter Months
because of a lack of energy collected by the solar panels to charge the batteries.
- 2022-07-12T12:00Z 2218/2 193 - 2023-06-17T08:00 2266/6 168
- In an attempt to reduce the power requirement in the winter the logger was reprogrammed in July 2022 to collect data
only during half of the day. The system is turned on or off every hour.
Measuring only half of the day resulted only in a minor increase in the noise level of 3 mm in the daily averages
compared to 2 mm in case of measuring for the full period. Unfortunately, the energy saving was not enough to
prevent the problem and the measurement series still suffers from large gaps.

- In May 2021, an adjustment was made to the antenna, resulting in a slightly higher position of the antenna.
